TO ALL WHOM IT MAY CONCERN:

Be it known that 1, DAVID S'rouonru-ol Dayton, in the county of Montgomery, in the State of Ohio, have invented a new and improved Combined Fruit-Drying House and Oven; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in an air-chamber to furnish heated air to the interior, and in lining the upper part of the oven with wood.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure 1 represents a perspective view of the furnace, and a sectional view of the oven and pipes.

Figure 2 represents a longitudinal section of the upper part of the furnace with a hot-air chamber.

Figure 3 represents a longitudinal section of the furnace with another form ofhot-air chamber.

A represents the oven with double metallic walls below, and with the upper part and top lined with wood, and having cleats and projections for drawers and pans. 0 represents a sliding partition, having a register, :2, in its centre, to regulate the admission of hot air from the part B to the upper part of the oven. The dotted lines at D represent the doors, F the furnace, and o the orifice through which the external air is admitted to the air-chamber; H, furnace-door; I, ash-pan; and K, register; E, the legs supporting the oven. The pipe M connects with the furnace at L, and at the upper end to the pipe N. This pipe serves to carry off the moisture from the drying fruit., The air issues at either end of the furnace, (see 0 0, fig. 3,) and passing up through the chamber 0 into the oven, the heat from the furnace heating the air as it passes through the chamber in its passage to the oven. Another form of chamber, P, is shown at fig. 2; it is connected to the front end of the furnace, and extending across the furnace and back it terminates in the bottom plate of the oven. At L L, figs. 2 and 3, are shown by dotted lines the opening in thcfurnace for the pipe. The grates extend the full length of the furnace, and the dotted lines on the ash-pan I, show the orifices for the admission of the air to the furnace. The process of baking and drying can be both accomplished at the same time, the baking being done in the part B, and with the intervening partition and lining of wood, which radiates heat less rapidly than metal, a low temperature is preserved above, while a temperature sufiiciently high is attained below. The

object in connecting the pipes M and N is to increase the draught through the oven to the more readily carry ofi" the moisture.

What I-claim as my invention, and desire to secure by Letters Patent, is

1. The metallic oven A, when the lower part is constructed with double walls, and the upper part is lined with wood, in the manner substantially as described and for the purposes specified. I

2. The air-chamber 0, when arranged with reference to the furnace F and oven A, in the manner substantially as described and for the purpose specified.
